SWEDEN' PACKAGE FOB RAZOR BLADES Applicationilled January 29, 1929, Serial No. 335,937,

All known packages for razor blades suffer from the drawback that the blade edges are easily damaged on inserting the blades into the packages or removing them' from the same. vEven if 'the edges have been manufactured with the greatest care this oiers no guaranty that the buyer of a bladepwill obtain it in a perfectly intact condition. onsidering the present method` of packing the blades, viz. by hand, the chances are that the razor blade will have been damaged long before it leaves the factory.

The present invention relates to a package where the razor blade edges are protecte against damage during blades, it being poss'ble according to the invention to eEect the packingby machine. In addition one gains the advantage that the risk of damage during the transport of the razor blades and on their being taken out o the package will be considerably lessened.

The invention, whichv for its application is dependent on the razor blades being provided with holes, recesses, channels, abutments, elevations, rid es or the like, is essentially characterized in securing the razor blades to the same is provided with vmembers engaging in the holes, recesses, channels or the like or embracing the abutments, elevations, ridges or the like.

To permit a convenient removal of the the securin me bers of the package so that the blades may by displacement preferably in a direction parallel to the edges. The package may then be devised so as to hold either a single razor blade or a varying number thereof in which latter case the blades should be provided on one side with ridges or the like extending in the llongitudinal direction, and on the opposits side with corresponding channels or the like.

Itis preferable that the razor blade or the pile of razor blades should be kept by suitable means in its displaced is most simply eiiected by a riction device. Such a device may either consist of springs he package and arranged to disposed in t bear against the razor blade or the outmost l d spective the insertion of the P f Figs. 2,

or the package may consist blade of the p ile,

of thin, elastic material so that it is resilient by itself. The preferably made in the shape of an enve ope, clamp or the like open at one or both ends, may in the last-mentioned case be provided with guiding members consisting of ridges, channels or the like, extending in the longitudinal direction and formed by means of pressing, rolling or the like.- may also be prevented from displacement in the package y their being made resilient.

In the attached drawings, Fig. 1 is a perview of a razor lade suitable for acking, whereas the other gures shown in the drawings represent di ereiit embodiments of a package manufactured according to the invention.

a One of these embodiments is shown in 3 land 4 viewed in plan, cross section and longitudinal section. Another embodiment is illustrated by Figs. 5 and 6, of which the former is viewe in plan and the A third embodiment an view, cross section an 8 and 9, a Jr'ourtli package,

is shown in pl itudinal section in Figs. 7,

and 12 in plan view and lon tudinal section, a sixth embodiment in Figs. 13 and 14, also in plan view and longitudinal section a seventh embodiment in Fig. 15 in cross section, and an eighth embodiment in Fig. 16 in cross section. A

The razor blade 1 has on one'side a longitudinal ridge 2 extending over the whole length of the blade. On the opposite side of the blade there is a corresponding channel king the ridge 2 by pressing 4 formed on ma or rolling the razor blade blank of uniform further thickness. The razor blade is shown to be provided with a central hole 3 as well as with two holes 5 serving to guide the blade normally in the shaving apparatus. Such a blade permits by suitable shape of the ridges 2 and channels 4 the pilin oi a lurality of razor blades on one anoter so that they support'themselves in the transversal direction, each ridge being suituated haniiel of the adjacent in a corresponding c blade. A pile thus formedl will have on on a certain distance from each one of its outer sides a longitudinal ridge extending over the whole length of the outer h blade and on its other outer side a corresponding channel 4, all edges being situated in two planes parallel with each other.

Such piles are shown in Figs. 2-9 to beinserted in packages 6 of elastic sheet metal, are provided for the purpose with openings 7 at one end, through which openings the pile is inserted, as well as with internal channels 8 at one side, said channels extending in the longitudinal direction of the package and being arranged so as to form guiding members for the ridge 2 on the outer side of the pile of blades. The packages are moreover devised in such a manner that their edges 9 extending parallel to the blade edges will be Situated at a suitable distance damaged on the blades being inserted into or removed from the package.

ln the embodiment shown in Figs. 2-4,

, where the package is made in the shape of an envelope or the like provided with a bottom 10, the pile of blades is kept secured in its inserted position by means of friction by springs l1 engaging one of the outer sidesof the blade pile, said springs being formed preferably by cut up portions, the longitudinal for the purpose in view may be positioned other. blades will be facilitated if the ends of the springs are further provided b with suitably bevelled portions 12 or the like. In order to permit the removal of one blade at a time from the package the distance between the longitudinal edges of the envelope should be chosen so that the uppermost razor blade may be conveniently actuated by pressure from outside. In consequence of the described effect of the springs the latter, independently of the height of the pile, may keep and protect not onl the original number of blades inserted ut also the minor number which may be left in the package after some of the blades have been withdrawn. Such a package can thus protect all moment when the last blade is removed from its package.

The insertion of the razor blades into the envelope is preferably effected by machine and by a member displaceably arranged on the same from a store consisting of bigger piles, the insertion taking place in a direction coinciding,r with the longitudinal direction of the blades or the ridges and channels.

his insertion will be facilitated. if'the bottom 10 is provided with a suitably arranged meansof a plunger or the like driven by the machine in such a manner that the springs are shoved aside on the insertion pile into the package.

. so that the latter of the blade Leeaeea ish for actuating the razor blades from the outside, said opening comprising only the middle portion of the one side, whereby the blade pile is kept between one side of the envelope and four abutments 14 arranged on the other side. In silience more suitable, if desired, these abutments may be varied as to their form, for instance, by means of cut up portions or the like 15. y

The modification in Figs. 7-9 shows a package made in the shape of a clamp, the elasticity of which is concentrated substantially to the bottom 10 of the package. The blades are thus in this case kept secured between the two shanks of the clamp, one of which Shanks is provided with a channel 8 for guiding the blades in the transversal direction, and the other with an opening 16 for the removal of the blades. One or both of the Shanks should further vbe provided with the longitudinally extending edges 9 for protection of the blade edges, said edges being preferably formed 'by ending the longitudinal edge portions of the Shanks upwards. For the insertion of the blades the ends of the shanks are moreover preferably provided with a rounded or bevelled portion 12 or similar.

Figs. 10-14 demonstrate packages which are especially adapted for packing each blade Fig. 10 shows such a package, congitudinal edges of the plate are bent, so that the edges of the blade are embraced by the same, and the blade edges are situated at a. suitable distance inside each bent edge 9, said bent edges being so arranged relatively to the channel that the elastic blade alters its shape during the insertion so that it will assume the position shown in the figure, whereby it will be kept by the package in its inserted position. The same result may be obtained if the plate is arranged to actuate the blade assumes a bent form in the longitudinal direction.

ln Figs. 11-14 similar which are contemplated which have no 'ridges or order to render the re-v the same.

rawing at 20 in order to the edge.

Figs. 13 and 14 show a package 6, which. simply consists of thin flexible material in the form of a band, yet .having sufficient iirmness, in which are provided two abutments 21 or the like engaging holes ofthe razor. blade, so that the blade when located on the same can be kept in its position by bending the band at the two ends of the blade as shown in the drawing. It may be preferable -to rovide the band with holes 22 corresponding to the abutments 21 and arranged manner that the abutments at the bent portion pass through the same, the band at its free end being formed as a lap23 or the like. The opening of' this package takes place quite simply by pulling the lap 23 becomes accessible and may be removed from the pins 21 or the like'. The material of the package may consist, for instance, of card-board or the like of thin quality in which case the fastenings of the razor blade maybe made in a simple manner after the blade has been put into place in the package, by making impressions or the like from outside into the card-board at the holes, 'the bending having been eected.

It is evident that also the packages in Figs. -14 may very well be arranged to hold a plurality of blades although t ey are mo adapted for protecting single blades. The shown embodiments may also be varied in many respects.' Thus the` opening 16for removing the blades from the package may very well be substituted by a ranged at the bottom and si es of the envelope, for instance, in the manner shown at 24 in Fig. 5. The' guiding members arranged in the package are also subject to certain variations. Thus the guidance of the razor blades may be eiected b ridges on of the package, said ri ges cooperating wit a channel or channels in the ad] acent bladev of the razor blade pile. Such an embodiment is shown in Fig. 15. The guidance may be brought about by a ridge or ridges arranged on one inside of the package and by a channel or channels correspon ingto the ridges and arranged on the other inside. Such an 4embodiment is shown in Fig. 16. the package should, however, in every case be arranged so that at least one of the insides,

in such a c so that the blade 'perforation ar- Preferably lwhich is -provided with guiding members, will be unperforated in order to obtain the best guidance possible of the razor blades in the transversal direction of the same.
